Flights to San Jose, Costa Rica

Costa Rica is one of our most-searched international destinations for a reason. The country is filled with lush rainforests, national parks (popular ones include Manuel Antonio and Arenal Volcano) and great beaches (snorkeling and diving in reefs is a very popular activity). Last week, CNN profiled top natural hot spring jungle resorts in Costa Rica, offering great ideas for travelers looking for a relaxing vacation. All-Inclusive resorts are always an option as well, although we recommend venturing outside the resort to check out the rainforests and other top attractions.

As for the deals to Costa Rica themselves, the following fares offer savings of nearly $200 on the regular prices and are available into May:

Cheap Flights to Las Vegas

According to a study conducted by the city’s Convention and Visitors Authority, 38.9 million people visited Las Vegas in 2011.

Though the article does not mention airfare, our primary goal at Fly.com is for travelers to spend less on flights in 2012.

Matt is an airfare deal hunter, whose amazing finds have been published in AM New York and NYTimes.com. He currently calls New York City home, but frequents Europe and the Middle East. His travels last year took him to Stockholm for $150 and Barcelona for $250 roundtrip, including taxes.

Do tell how you got those Europe fairs? $150 to Stockholm? that can’t be true?

Good question, @twitter-498293561:disqus . It’s extremely rare to find fares like that. We found it while researching deals to include on our @fly_com:twitter twitter deal feed. Usually fares like that are mistakes by the airlines, so it is important to book them ASAP. Airlines tend to catch their mistake after an hour or two, which is why we always urge our users not to wait when they find a great fare.

It definitely seems too good to be true, but I attached my itinerary as proof. I actually just returned from Brussels. That one cost $232 roundtrip including taxes.
